Gratiano speaks an infinite deal of nothing, more than any man in Venice;
but his reasons are as two grains of wheat in two bushels of chaff; you seek
all day ere you find them; and when you have them, they are not worth the
search.
-- Shakespeare

INSTRUCTIONS: These hint grids reveal the order in which the squares were solved by my computer. It's not necessarily
the same order you would use, but it's probably close. Follow the numbered squares in order 1,2,3,... until you find
a square you haven't solved yet. This square (or the one or two immediately after it) is a good candidate to solve next.
